<h3>Create MODIS L1C Data</h3>
<p>MODIS L1C data is not a standard format. It has been defined in the the frame of ESA OC-CCI project. It contains all the data required by the
    processor,
    the more accurate geo-location and also the sun and view angles.<br>
    The data can be generated with l1gen of SeaDAS (
    <object classid="java:org.netbeans.modules.javahelp.BrowserDisplayer">
        <param name="content" value="https://seadas.gsfc.nasa.gov/">
        <param name="text" value="https://seadas.gsfc.nasa.gov/">
        <param name="textFontSize" value="bigger">
    </object>
    ).
